Corteva’s share price fell about 84% in a single session on October 1, making it one of the most-watched tickers in the US. But shareholders did not lose most of their money: the agricultural company split in two, and every Corteva share came with one share of a new seed company, Vylor.

Key takeaways

• Corteva completed the spin-off of its seed business, now called Vylor (NYSE: VYLR), on October 1, 2026. Holders received one Vylor share for each Corteva share.
• Corteva’s price dropped from the high $70s to about $12.57 because the bigger part of the company now trades separately. Vylor closed its first day at $67.74.
• Some US states are still challenging the split in court over potential PFAS (“forever chemicals”) liabilities, which Corteva rejects.

Why everyone is talking about it

A large S&P 500 company appearing at the top of “biggest losers” lists with a drop of more than 80% looks like a corporate disaster. Corteva led Yahoo Finance’s trending tickers on Friday morning for exactly that reason. Many people searching for the stock are investors, retirement savers holding index funds, or farmers who know the company’s Pioneer seed brand, and they want to know whether something went badly wrong. It did not. The fall is a mechanical effect of a spin-off, a type of corporate split that regularly confuses price charts and portfolio apps.

The facts so far

Corteva announced the plan on October 1, 2025, and its board approved the distribution in September 2026. According to the company, anyone who held Corteva stock at the close of business on September 24 received one share of Vylor for each Corteva share. The distribution was completed before the market opened on October 1. Shareholders get cash instead of any fractional shares, and Corteva says the transaction is intended to be tax-free for US federal income tax purposes, apart from that cash.

The two companies now look like this:

• Vylor (seeds and genetics), based in Johnston, Iowa, and led by former Corteva chief executive Chuck Magro. It is targeting $11.2–11.9 billion in net sales and $3.3–3.7 billion in operating EBITDA by 2029, and it plans to expand licensing of its seed technology to other companies.
• Corteva (crop protection and digital products), based in Indianapolis and led by chief executive Luke Kissam. It keeps the herbicides, insecticides and fungicides business, along with the digital tools farmers use to manage it.

Corteva shares closed at $77.87 on September 29 and at about $12.57 on October 1, down roughly 84% on the day. Vylor started trading with a reference price of $66 and closed its first session at $67.74, up about 2.6%.

The split happened despite legal challenges. A federal judge in South Carolina rejected California’s emergency request to delay it. Separately, a group of states has filed a lawsuit in an Indiana state court alleging that the structure is designed to shield the seed business from PFAS liabilities, which Corteva partly inherited from its DuPont past. Corteva calls the claims “speculative and unproven” and says it never made or sold PFAS products. That case continues.

The background

Corteva itself was born out of a split: it was spun out of DowDuPont in 2019. A spin-off happens when a company hands shares of one of its divisions directly to its own shareholders, creating a second listed company. No new money changes hands. The same assets are simply put into two separate “boxes.”

Think of a pizza cut into two unequal slices. Before the cut, you own the whole pizza. After the cut, you own both slices. If someone only weighs the smaller slice, it looks as if most of your pizza vanished. Here the seed business was the bigger slice, so the remaining Corteva shares now represent a much smaller company, and their price reset lower.

Companies usually split to let each business run its own strategy, budget and debt load, and to let investors value them separately. Seeds and genetics tend to have higher margins and steadier growth than crop chemicals, which is why the market values Vylor more highly.

What it means for your money

If you held Corteva on the record date, directly or through a fund, you should now hold Vylor too. Here is a simple worked example using the closing prices above:

• Before: 100 Corteva shares × $77.87 = $7,787.
• After: 100 Corteva shares × $12.57 = $1,257, plus 100 Vylor shares × $67.74 = $6,774. Total: $8,031.

Prices moved over those days, so the totals differ a little, but the combined value stayed in the same range. Some broker apps take a day or two to show new shares, and some charts show an “84% loss” until they are adjusted. Your original purchase cost (cost basis) is normally split between the two holdings for tax purposes. Companies usually publish guidance on this after a spin-off, so check your broker statement before you sell either stock. Index funds that tracked Corteva adjust their holdings on their own.

This is general information, not financial advice.

What to watch next

• How the two stocks trade over the coming weeks, as funds that do not want one of the halves sell it.
• Each company’s first quarterly results as a standalone business.
• The state-led PFAS lawsuits over the split, and any guidance on how to allocate cost basis.
• The wider market backdrop: high borrowing costs are weighing on stocks (see why bond yields hit a 2007 high) and on big moves like Accenture’s jump this week. Upcoming data releases are in our economic calendar.
